Question

这刚刚开始。直到今天下午，我已经能够在我的项目目录中运行mvn clean install而没有任何问题。我今天下午试图这样做，并得到以下错误：

MusikPolice$ mvn -X clean install

它建议我阅读的维基页面并不十分有用，只是暗示如果Maven无法写入~/.m2/repository/目录，可能会发生这种情况。

还有其他想法吗？

由于此日志消息：

[INFO] Error stacktraces are turned on.
[DEBUG] Reading global settings from /Applications/apache-maven-3.1.1/conf/settings.xml
[DEBUG] Reading user settings from /var/empty/.m2/settings.xml

似乎Maven之后有红色/Applications/apache-maven-3.1.1/conf/settings.xml开始阅读/var/empty/.m2/settings.xml，因此如果以下行已取消注释，请检查/Applications/apache-maven-3.1.1/conf/settings.xml：

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->

并将localRepository设置为/var/empty/。

Maven试图使用/var/empty/.m2/repository作为我的本地存储库
